Description

The event itself contains all the data the consumer needs. The consumer doesn't need to contact the producer for more info.

Where to use

• High decoupling.
\n
• Reducing network chatter.

Real World Example

The 'OrderCreated' event includes the full item list, shipping address, and total amount. The Shipping Service can generate a label without calling the Order API.

Code Example

class Event-CarriedStateTransfer:
    def __init__(self):
        pass

    def execute(self):
        print('Executing Event-Carried State Transfer')
